Toyota FT-86 Concept exhaust note – Click to watch the video after the jump

Toyota garnered a lot of attention at this year's Tokyo Motor Show with the debut of the FT-86 concept. And they weren't about to let it slip past them, either. As part of the spectacle, they played the sounds of the prototype supposedly rounding the Nürburgring.

The FT-86 is being jointly developed by Toyota and Subaru, the former providing the platform and the latter the engine, among other components. The thing is, as our JDM-loving compatriots over at 7Tune point out, the engine noise piped in doesn't sound much like a boxer four.

Of course, that kind of deducing poses more questions than it answers: Is Toyota planning a different engine for its version of the so-called Toyobaru sports-coupe? Is Subaru's hesitation prompting Toyota to make its own plans? Did they not like how the engine sounded and opt to pipe in another soundtrack altogether? We can only speculate, but if you listen to the audio in the video clip after the jump and have your own idea, we're all ears.

      Sounds like they are looping a sound clip from Gran Turismo. GT is famous for the 1 engine sound tweaked just a little bit to sound different from each other (but they never do). The Subi's in that game never sound like one, and the v8s barely sound any different from the small engined cars. That was always my 1 complaint of that game (well I guess I always wanted damage too)..

      Ever heard of equal length headers?
      • 5 Years Ago
      Maybe both Toyota and Subaru are developing a new boxer IMO. Hope it will give an amazing output.
      • 5 Years Ago
      wow, sounds like a lawnmower sent through a synthesizer.
      • 5 Years Ago
      Uh, it didn't sound like a boxer when you posted a video of it tire squealing its way around a corner either.

      Why are you surprised now? Did you think it would sound different from then?
        • 5 Years Ago
        I'm just praying for a 3JZ-GTE!
        If Toyota slaps a hot inline 6 in there, that would be absolutely awesome. Even if it was a high-revving NA engine, similar to the E46 M3, that would be pretty cool

      Maybe Toyota's announcement about pulling out of F1, means they might be thinking about a rallying return, and maybe the FT-86 is a platform they might look at?

      But hey maybe that's just wishful thinking on my part.

      it sounds like the engine noise and tire screeching are just borrowed sound effects from "initial d" which is pretty much responsible for toyota even thinking about bringing back a successor to the AE86 that started in the series.

      Amazing that the exhaust remains perfectly still when the car is revving.
        • 5 Years Ago
        I'm pretty sure that the car in the video is not running...

      What if it's a yet-to-be-announced flat 6 from Subaru? A SVX revival?
      • 5 Years Ago
      A simple thing called equal length headers. An unequal length header is what produces the boxer rumble.
        • 5 Years Ago
        DING DING DING DING DING!

        Tell him what he's won, Johnny...

        the "boxer sound" is common on the subarus, especially the turbos with largely different exhaust runs, due to the un-equal length.

        The non-turbo engines are more symmetrically disposed, not having to reach over to the side for a turbo. Even the '10 Legacy and Boxer Diesel are front-mounting their turbos, for equal length exhaust runs.

        An equal length H4 is not going to sound much different than an equal length header I4.

        If anything, an equal length H6 will sound smoother than an equal length V6 with a crank pin offset, and thus an uneven firing order.
        • 5 Years Ago
        It isn't just 'equal length' it is firing order.
        Subaru, on the naturally aspirated 2.5 cars [in the past], used to match the cylinders on the banks, and then match those two pipe into one pipe.
        Everything was equal in length, yet it still went blub blub blub blub, due to the L L R R firing order.


        What odd firing V6s are you talking about? Are there any still around.
        • 5 Years Ago
        Boy, I almost forgot what proper geekdom (especially Subaru geekdom) was like - thank you for renewing my faith in mankind guys. :-)

        "Theoretically the exhaust sound from equal length runners would not differ, unless the engine vibration translated into something rattling or buzzing from the engine's vibration."

        ...which it will on every damn Subaru. My car is such an awful rattle-trap.
        • 5 Years Ago
        I agree, put equal lengths (manifold) on a subaru, and it sounds like any other 4-banger out there. The unequal manifold is DEFINITELY what causes the notorious Subie Rumble.
        • 5 Years Ago
        ^^What they said. Lord I can't believe this is an autoblog........
        • 5 Years Ago
        Actually, I was wrong... I was thinking that an offset crank pin in a V6 would make the firing order odd... it actually makes the firing order even at 120 degrees of crank rotation.

        But it makes the engine less balanced, and not as smooth in terms of vibration, compared to an inline, or especially a flat 6. Theoretically the exhaust sound from equal length runners would not differ, unless the engine vibration translated into something rattling or buzzing from the engine's vibration.

        -----
        Back on topic with a little speculation... there are rumors that the FT-86 Toyota/Subaru project may have a new generation flat four, possibly derived from the EZ30R engine type, minus two cylinders.

        It is possible that engine may have changed it's firing order to L-R-L-R, and without a turbo, it is likely that the exhaust is symmetrical, and equal length.
      • 5 Years Ago
      All of the turbos Subaru uses in Japan are twin scroll units which require the equal length exhaust manifolds and eliminate the boxer rumble. Since this is going to be a 2.0L as well, I suspected that they would introduce the twinscroll on this as well, and the exhaust note would not be odd for a Toyota.

      I would love to see a come back of the tough as nails 3SGTE in a more high tech modern installment. Light weight, proven reliability under pressure and high horsepower capabilities.
